[Suppression of proliferative allogenic response in patients receiving a programmed series of transfusions prior to renal graft].
The effects on the lymphocytic proliferative allogenic response of a protocol of planned blood transfusions have been studied in 12 patients with chronic renal failure. This study was prospective and the experiments were performed before kidney grafting. The results were then compared with the clinical results of the graft. These results have shown that the peak allogenic proliferation in the group of patients with good renal function was significantly decreased after transfusion. This decreased response was not observed in the groups of patients with either kidney rejection or immunisation and antibody formation. Most of the lymphocyte suspensions whose proliferation was decreased after transfusion were also capable of inhibiting the proliferation of autologous lymphocytes taken before transfusion. It is therefore legitimate to postulate that the decreased response was due to the generation of suppressor lymphocytes. This latter could be responsible for the beneficial effects of blood transfusion on kidney grafting.
